There are stories about shitty warranty service from about any manufacturer. I’ve been there, unfortunately, more than once.
My 2013 mustang developed a transmission noisy on the infamous mt82 6 speed manual and I took it to the dealer. I was told it was normal, which I told them was BS. Took it to two more dealers after that and got the run around so I gave up. At 60k plus miles (a couple thousand miles after power train warranty was up) the piece of junk died and I had to buy another an do the work myself.
Bought a 2007 Camry with the 4cyl. 2az-Fe new and at 10k miles noticed oil level had dropped some. I thought I was losing my mind. It was a new car after all, so how could that be?. I kept a close eye and, sure enough, car was burning oil. I asked the dealer and they looked at me as if I was crazy and said all was fine. After 7 years and 80k miles the car was burning 2 plus quarts between oil changes. Toyota finally sent me a letter basically admitting what I had been complaining about all along. They had so many vehicles coming in with excessive consumption or seized engines that they had started a “program” offering everyone one with less than 150k miles/10 years the option to bring their vehicle in for an oil consumption test and, if it failed the test, they would take motor apart and replace pistons and crappy low tension rings at no cost. I was excited and took my car in just be told that, after the test, my car was not going to be repaired because it wasn’t burning a quart every 1100 miles.
! This one left such a bad taste in my mouth that I didn’t buy another Toyota until recently.
